TI中文支持网请教专家:
我用样板工程 28335_IQsampleC 测试 _IQNtoa 转换函数没有出问题.
但在我的工程中加入
_iq14 fx;
_iq3 fl;
float j = 35.65456;
char buffer[10];
……….
fx = _IQ14(j);
fl = _IQ3int(fx);
_IQ14toa(buffer, "%6.6f", fx);
………
编译时出提示:"../CMD/My_F2835.cmd", line 177: warning: no matching section
并报错:
Severity and Description Path Resource Location Creation Time Id
unresolved symbol __IQ14toa, first referenced in ./INCLUDE/ExInt.obj My_Dsp_Projects line 0 1370539831250 4466
去除 _IQ14toa(buffer, "%6.6f", fx); 这行则只出上面提示.可通过编译.
我试着 多次修改CMD文件.都无法去除提示.我感觉去除提示则转换函数就可通过.请专家指点是什么问题.
CMD文件如下:

楼主能否透露一下，这个问题最后怎么解决的，如今又有人遇到了类似的问题，不知道怎么办。
